These strips of paper Figure 2 is a side elevation of the apparatus may be fed from a roll or from a pile into which showing the platen of a typewriter with the strips the strips are folded. Each strip of paper has of paper and the sheets of carbon in position for cross serrations I1, along which it may be torn writing. for removing sections, and adjacent each serra- 40v 40 Figure 3 is avieW similar to Figure 2, but showtion is a. plurality of file holes I8. These ing the strips of paper and the carbon sheets iile holes are adjacent the serrations, as shown in a supported position after the writing has been in Figure l. The platen of the typewriter is produced on the strips of paper. In this gure indicated by the numeral I9, and is used for the carbon sheets are in a position to be'withfeeding the strips of paper, with nthe interposed 45 drawn and the strips of paper torn oli for further sheets of carbon. The sheets of carbon paper are. writing. indicated by the numeral 20, one of which Figure 4 is a section on the lined-4 ofFigure l. is illustrated in Figure 6, and each of which Figure 5 is a section on the line 5 5 of Figure 1. has on one end a cardboard supporting strip 2|, Figure 6 isa view showing a carbon sheet with which extends laterally behind the edges of the 5o supporting 'cardboard on one end thereof. sheet of carbon.

This attachment has a rectangular supporting For supporting the sheets of carbon by means frame composed of side bars I and transverse of the cardboard strips a metal strip 22 is procross bars 2 attached at their ends to the side bars vided, which has attached to each end one A,end

Y so there is formed a substantially rigid rectanguof a. metal tape 23, the other end of which m'etal 55 tape being attached to a drum 23EL in a groove 24 located in the periphery of the drum. In the bottom of the groove there is a pocket 25 into which one end of the metal tape ts, for holding the tape on lthe drum. 'I'hese drums, two in number, one at each side of the frame, are supported by an operating shaft 26, which has on one end, without the frame, a crank 2l with a.` handle 28 thereon. This crank and handle are for the purpose of rotating the drums to take up the metal tapes. Adjacent each end of the metal strip 22 is a pin 29 adapted to pass through a hole in the end of the cardboard strip 2|.

When the desired number of strips are assem-I I bled, between each adjacent strip is placed a sheetVv sheets of carbon are supported from the drums.

by the metal tapes.

For the purpose of holding the strips of paper and the sheets of carbon in a compact condition with relation to each other, there is provided a clamp strip 30, which has in each end a notch 3l. After the paper has been assembled this strip is bowed so that each end will receive in its notch a pin 29. When the pins are properly seated in the notches the clamp strip will lie against the face of the outside strip of paper. Extending from each side bar is a horizontally disposed bracket 32. These brackets are connected at their free ends by means of a cross bar 33, which has thereon forwardly extending pins, as showny in Figure 1.

When a certain length of the strips of paperl has been used the strips are supported by means of the pins 34 passing through the le holes I8, in the manner shown inFigure 3. At this time it is desired to withdraw the sheets of carbon so they` will be ready for use in connection with another section of the strips of paper. In order to withdraw the sheets of carbon, drums are rotated by means of the handle 28. By rotating the handle the strips of carbon are withdrawn to the position shown in Figure 2.

After the sheets of carbon have been withdrawn the free ends of the strips of paper may be torn off along the serrated lines. When the strips are torn off the carbon will extend around the platen not quite to the le holes I8, and to a point 35, as indicated in Figure 1. The strips of paper above the serrations Il, shown in the lower end of Figure l, are torn off. When the strips are thus torn off the paper is in the condition shown in Figure 2 and is ready to be used for typewriting purposes. After the desired amount of typewriting has been done the strips of paper, with the interwoven sheets of carbon therebetween, are in the position shown in Figure 3. 1

In connection with the shaft 26 and the drums 23a there is provided a. coil spring 36 around the shaft, attached at one end to some suitable part of one of the drums or to the shaft, while the other end is attached to some part of the frame. This spring may be used as a counterbalance spring to hold the carbon sheets in a tense condition while they, together with the strips, are

being fed around the typewriter platen. It also aids in the withdrawal of the strips after the typewriting has been finished on a certain section of the strips of paper. vThe point to which the sheets of`carbon extend in Figure 3 is indiitis desired to withdraw the sheets of carbon this roller is removed from contact with the stri-gs so that the carbon sheets may be easily withdrawn for further luse in connection with another section of the strips of paper.

It will be understood that I desire to comprehend within my invention such modifications as come within the scope of my claims and my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
